    Abstract: A compressor control device includes a driving circuit, for controllably supplying a coil of an electric motor of a compressor. A temperature sensor is thermally coupled to the driving circuit and provides a temperature sensing signal correlated to a temperature in the driving circuit. A control stage, coupled to the driving circuit and to the temperature sensor, selectively prevents the driving circuit from supplying the coil, in response to a minimum temperature increment being detected by the temperature sensor within a pre-determined control time window.
